【问题描述】：

我正在开发一个应用程序，我必须将联系人保存在通讯录中，但如果联系人已经保存在联系人中，则不应保存。

但我不知道

任何帮助将不胜感激。

提前致谢。

【问题讨论】：

我认为您需要先获取所有联系人，然后需要在该联系人中找到一个号码。检查这个***.com/questions/19027118/fetch-contacts-in-ios-7

这是一个很好的tutorial 用于获取手机的联系人列表，然后使用它你可以检查是否添加..

为什么投反对票？我找到了路。

【参考方案1】：

已解决问题

 -(void)CheckContactIsExits
  ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);

NSArray *allContacts = (__bridge NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);

ABRecordRef pet = ABPersonCreate();
ABRecordSetValue(pet, kABPersonFirstNameProperty, (__bridge CFStringRef)@"VoxSci Activation", nil);

for (id record in allContacts)
    ABRecordRef thisContact = (__bridge ABRecordRef)record;
    if (CFStringCompare(ABRecordCopyCompositeName(thisContact),
                        ABRecordCopyCompositeName(pet), 0) == kCFCompareEqualTo)

        NSLog(@"The contact already exists");
        //The contact already exists!
        isContactExits=YES;
    

【讨论】：

它在行崩溃（CFStringCompare(ABRecordCopyCompositeName(thisContact)，出现 EXC_BAD_ACCESS 错误..请您帮忙

【参考方案2】：

假设您为此使用 Apples 框架，您的用户将可以选择“创建新联系人”或者如果它已经在联系人列表中“添加到现有联系人”。因此用户可以决定是否应该添加它

【参考方案3】：

#import <AddressBook/AddressBook.h>
#import <AddressBookUI/AddressBookUI.h>

并读取iPhone中的所有联系人并检查姓名或电话是否退出。

【参考方案4】：

通过联系电话检查联系人是否退出

注意：仅将 checkingPhoneNumber 变量替换为您的检查联系人号码

ABAddressBookRef * addressbook = ABAddressBookCreateWithOptions(Nil, Nil);
NSArray *people = (__bridge NSArray*)ABAddressBookCopyArrayOfAllPeople(addressbook);
NSMutableArray *phoneArray=[[NSMutableArray alloc] init];

for(id person in people)

    // get person contact number
    ABMultiValueRef phones = (ABMultiValueRef)ABRecordCopyValue((__bridge ABRecordRef)(person), kABPersonPhoneProperty);
    NSString* mobile=@"";
    NSString* mobileLabel;

    for (int i=0; i < ABMultiValueGetCount(phones); i++)
    
        mobileLabel = (__bridge NSString*)ABMultiValueCopyLabelAtIndex(phones, i);
        if([mobileLabel isEqualToString:(NSString *)kABPersonPhoneMobileLabel]) 
            NSLog(@"mobile:");
         else if ([mobileLabel isEqualToString:(NSString*)kABPersonPhoneIPhoneLabel]) 
            NSLog(@"iphone:");
         else if ([mobileLabel isEqualToString:(NSString*)kABPersonPhonePagerLabel]) 
            NSLog(@"pager:");
        
        mobile = (__bridge NSString*)ABMultiValueCopyValueAtIndex(phones, i);
        NSLog(@"%@", mobile);

        // remove all spaces bracket from contact number
        NSMutableString *newPhoneStr = [[NSMutableString alloc] init];;
        int j = [mobile length];
        for (int i=0; i<j; i++)
        
            if ([mobile characterAtIndex:i] >=48 && [mobile characterAtIndex:i] <=59)
            
                [newPhoneStr appendFormat:@"%c",[mobile characterAtIndex:i]];
            
        
        //add contact into phoneArray
        [phoneArray addObject:newPhoneStr];
    

NSLog(@"%@",phoneArray);

BOOL identicalStringFound = NO;

// remove all spaces bracket from contact number which is check
NSMutableString *newCheckingPhoneNumberStr = [[NSMutableString alloc] init];
int j = [checkingPhoneNumber length];
for (int i=0; i<j; i++)

    if ([checkingPhoneNumber characterAtIndex:i] >=48 && [[profileDetailsDict valueForKey:@"mobile"] characterAtIndex:i] <=59)
    
        [newCheckingPhoneNumberStr appendFormat:@"%c",[checkingPhoneNumber characterAtIndex:i]];
    


for (NSString *contact in phoneArray)

    if ([contact isEqual:newCheckingPhoneNumberStr])
    
        identicalStringFound = YES;
        break;
    

if(identicalStringFound)

    // checkingPhoneNumber is exit 

else

    // checkingPhoneNumber is not exit 
 

【参考方案5】：

如果有人想检查姓名是否保存在通讯录中，那么下面的功能可能会有用：

-(BOOL)isNameSaved:(NSString*)strGivenName 
    BOOL isSaved = NO;
    ABAddressBookRef addressBook = ABAddressBookCreate();
    CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
    CFIndex nPeople = ABAddressBookGetPersonCount(addressBook);
    for ( int i = 0; i < nPeople; i++ ) 
        ABRecordRef ref = CFArrayGetValueAtIndex(allPeople, i);
        CFStringRef firstc = (CFStringRef)ABRecordCopyValue(ref, kABPersonFirstNameProperty);
        NSString *first = [NSString stringWithFormat:@"%@",firstc];
        if ([first isEqualToString:strGivenName]) 
            isSaved = YES;
            break;
        
    
    return isSaved;
